None of the current vaccines for SARS-CoV-2 prevent the contraction or spread of covid-19,even with boosters.
What’s worse, according to the Danish and Bangladesh studies, masks are at best 15-20% effective.
That’s an oversimplification, imo. Had the government not aided the airlines they wouldn’t be here, at least not in any sizable way, when travel was allowed to return.
My wife traveled to Germany last week. Other than a questionnaire there was no other screening, not even a temperature check.
Last month traveling through Lihue Hawaii our crew had to fill out 2 questionnaires(one digital and one paper), temperature checks on arrival and departure, and we were not allowed to leave the hotel grounds.
There’s no way to tell if any of those who actually test positive later for coronavirus came into contact on the aircraft.
Regarding eating and drinking on the aircraft, the passenger safety videos may not be updated with relevant instructions but flight attendants do say masks should stay on unless eating and drinking or if the need arises to use the drop down chemical oxygen masks with a separate PA.
